Introduce `CaseSym`?

[mlutze]

Cases are currently simply Idents. It would be more consistent with our other declarations to give them proper symbols.

What about fields and predicates? I think they get a name but not a symbol.

But those are for structural types. You can't point to a field and say "this is where it is declared"

Fair point. In that case I am sold.

This becomes a little scary as the EnumSym + Name.Tag pattern goes all the way to the backend.

I think its many changes, but all of them trivial. We don't mess with tags.
